I have finally picked up a Lee Pro 4-20 pot to start casting bullets on my own, rather than at a nearby friend's house. I have read up on the "How's" and such, and have several bullet and ingot moulds, but I don't know where to find a high temp thermometer. Is this necessary, or is it just a trial and error until you find the right setting on the dial and the right amount of time in the pot?
Any help would be greatly appreciated.
